Adam Ulivi from Memory Card Zoo sent me a Samsung 8Gb micro SDHC class 4.
Seems like a regular SD card but they claim to be water proof, shock proof and magnet proof.
I ran a few tests using SD Tools for Android to compare it against the others cards I have around. The result:
The general raw output data collected from SD Tools:
| Write Speed (Mb/s) | Read speed (Mb/s) | |
| SanDisk Class 4, 8Gb | 4.1 | 11.7 |
| Samsung Class 4, 8Gb | 5.5 | 17.9 |
| Patriot Class 10, 16Gb | 8.1 | 20.1 |
I use the SanDisk in my Android and Patriot on my camera. It would be a good combo have a waterproof card on my waterproof camera but this sd card can not beat a class 10 card. I may change my cellphone’s memory card for this Samsung.
If you want to try to yourselft this or others models of Micro SD card visit their store. Thank you Adam!

Openpixels is a project of mine to create a free and open source artistic framework for game projects in any language or platform. It is going pretty well.
You can just download a zip or tar.gz of the latest version.
You may want fork it or get a git working copy of it to later make your own contributions to the project. In this case:
apt-get install git-core cd ~ git clone git://github.com/silveira/openpixels.git
You will see something like this:
Cloning into openpixels... remote: Counting objects: 129, done. remote: Compressing objects: 100% (126/126), done. remote: Total 129 (delta 17), reused 0 (delta 0) Receiving objects: 100% (129/129), 784.52 KiB, done. Resolving deltas: 100% (17/17), done.
And now you have a repository clone at ~/openpixels and you can start hacking.
